Our best-selling L20 completely renewed A machine synonymous with the history of Cincom has been designed for the new age with 4 models in modular design. Ranging from a 5-axis machine with excellent cost performance to a high-end machine equipped with B axis and a back spindle Y axis, you can select the machine according to the functions you require. This concept offers unrivalled versatility with two types of gang tool post, five types of opposite tool post and three types of back tool post are available to be specified according to the functions required. 02 Cincom L20
Stable, powerful, and highly productive with versatility of modular design With the current shift in manufacturing industry, the requirement is for variable-lot machining of a wide range of workpieces. In order to meet this requirement, Citizen has introduced modular design. We allow the selection of functions corresponding to a diverse range of machining needs, and help customers to optimize their manufacturing by combining these functions to achieve their ideal machine configuration. Guide bushing-less type Guide bushing type L20 Type XII Example tooling Ability to use as a guide bushing type or guide bushing-less type by switching between them Either type can be selected as appropriate, when machining long, thin workpieces, when using cold drawn material, and in order to leave short remnant bars. Option 20 25 20mm max. bar as standard; 25mm as option Supply of bar stock up to 25mm is supported as an option. The machining length per chucking is 200mm (20mm) and 188mm (25mm). The long workpiece unit (option) supports workpieces up to 20mm. L20 Type VIII Example tooling Cincom L20 03

Intuitive screen display is readable at a glance Equipped with high-speed NC The machine is equipped with the latest NC model to drastically reduce the start-up and screen switching time compared to conventional machines with advanced functions. On-machine program check function Using manual handle feed, operations can be run in the forward or reverse directions, and you can temporarily stop program operation, edit the program, and then restart operation. Display of easily understood illustrations Illustrations appropriate for each item are displayed. You can see what they mean at a glance (the screen shown above displays the machining data). Display of code list The function displays the list of G and M codes including explanations to aid programming. Eco screen The current power consumption is shown on the screen, along with the cumulative power consumption, and the power regeneration (generation) status. Eco screen (example graph display) The machines power consumption can also be shown in the form of an easy-to-understand graph. The next process starts before the current one ends Cincom Control saves time between processes Cincom Control We have developed a new control system unique to Citizen that realizes fast and smooth operation. It reduces idle time and achieves faster rapid feed together with substantial shortening of cycle times. Multiple tool post overlapping function Independent opposite and gang tool posts are provided. In front machining, idle time has been completely eliminated by using a unique control method whereby the tool post to be used next starts the preparation for machining without waiting for the other one to complete its retraction operation. Direct spindle indexing function This substantially reduces spindle indexing time. When indexing the spindle, this function allows the spindle to be decelerated and stopped at the required index position by specifying this position with a C-axis command while the spindle is rotating. This eliminates the idle time up until rotation stops, and improves working efficiency. Conventional machine Stop rotation Zero point return 1. Retraction operation Rotating Indexing L20 2. Tool post motion starts in tandem with the retraction operation Rotating Direct indexing Indexing 06 Cincom L20
